Materials Data on Ba3FeRu2O9 by Materials Project
Ba3FeRu2O9 is (Cubic) Perovskite-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with nine BaO12 cuboctahedra, corners with three equivalent FeO6 octahedra, faces with seven BaO12 cuboctahedra, a faceface with one FeO6 octahedra, and faces with six RuO6 octahedra. The corner-sharing octahedral tilt angles are 7°. There are a spread of Ba–O bond distances ranging from 2.84–2.99 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with nine BaO12 cuboctahedra, corners with three equivalent RuO6 octahedra, faces with seven BaO12 cuboctahedra, faces with three equivalent FeO6 octahedra, and faces with four RuO6 octahedra. The corner-sharing octahedral tilt angles are 11°. There are nine shorter (2.91 Å) and three longer (2.99 Å) Ba–O bond lengths. In the third Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, faces with three equivalent FeO6 octahedra, and faces with five RuO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.89–2.96 Å. There are two inequivalent Ru+4.50+ sites. In the first Ru+4.50+ site, Ru+4.50+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with three equivalent RuO6 octahedra, corners with three equivalent FeO6 octahedra, and faces with eight BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 1–5°. There are three shorter (1.99 Å) and three longer (2.01 Å) Ru–O bond lengths. In the second Ru+4.50+ site, Ru+4.50+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, corners with three equivalent RuO6 octahedra, faces with seven BaO12 cuboctahedra, and a faceface with one FeO6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are three shorter (1.99 Å) and three longer (2.01 Å) Ru–O bond lengths. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, corners with three equivalent RuO6 octahedra, faces with seven BaO12 cuboctahedra, and a faceface with one RuO6 octahedra. The corner-sharing octahedral tilt angles are 5°. There are three shorter (1.99 Å) and three longer (2.11 Å) Fe–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four Ba2+, one Ru+4.50+, and one Fe3+ atom to form a mixture of distorted corner and face-sharing OBa4FeRu octahedra. The corner-sharing octahedra tilt angles range from 7–60°. In the second O2- site, O2- is bonded in a distorted linear geometry to four Ba2+ and two Ru+4.50+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four Ba2+, one Ru+4.50+, and one Fe3+ atom.
